== 522 的根因 ==
DNS 配好、橙色云朵生效之后:
http://yk.xxmxxs.top/ -> 200(经 Cloudflare,反代正常)
https://yk.xxmxxs.top/ -> 522
13.54.30.196:443 -> 不通
zone 的 SSL/TLS 模式是 **Full / Full(strict)**,Cloudflare 回源走 443,
而源站只听了 80 —— 因此 522。
== 解决:源站签 Let's Encrypt 证书 ==
用 certbot 的 nginx 插件签(**不需要 webroot**,插件自己处理挑战):
Successfully received certificate
/etc/letsencrypt/live/yk.xxmxxs.top/fullchain.pem
notAfter = Jan 6 2027(自动续期已启用 certbot.timer)
nginx 已加 listen 443 + 证书 + http->https 跳转
**开着橙色云朵也能签**:HTTP-01 挑战请求
http://yk.xxmxxs.top/.well-known/acme-challenge/... 会经 Cloudflare
回源到 80,CF 不缓存该路径、会透传,所以验证能过。
比"先关云朵签完再开"省事,也不用等 DNS 传播。
踩的坑:第一次用了 xmz7891@example.com,Let's Encrypt 拒收
example.com 这类保留域名,报"invalid email"。
改用 --register-unsafely-without-email 即可
(续期由 timer 负责,不依赖邮件提醒)。
== 停掉旧服务器 ==
中转已在 Lightsail 跑通,旧那台(随身 WiFi + 两条 CF 隧道 + 网络调优)
全部停掉并取消自启:
lanremote-relay / lanremote-tunnel / lanremote-tunnel-h2 /
lanremote-nettune / monitor.timer / watchdog.timer -> 全 inactive
**只停服务,没关机、没删文件** —— 保持可逆,新服务器稳几天再说。
== 待用户操作 ==
Lightsail 防火墙开 TCP 443(Cloudflare 的 Full(strict) 回源要用)。

r'''验证源站的 443 是否就绪(证书签完之后)。
|
||
|
||
背景:522 是因为 Cloudflare 的 SSL 模式是 Full/Full(strict),
|
||
回源走 443,而源站只有 80。现在证书签好了、nginx 也配了 443,
|
||
所以要确认:
|
||
|
||
1. 本机 443 能自测通(带正确 SNI)
|
||
2. 从**外面**能不能连上 443
|
||
—— 这一步取决于用户在 Lightsail 防火墙开没开 443
